To all whom it may concern: Be it known that I, ROBERT S. BRIQKEY,

acitizen of the United States, residing at Aberdeen, in the county of Brown and State of South Dakota, have invented certain new and useful Improvements in Automobile- Heaters'; and I do hereby declare the folj lowing to be a full, clear, and exact descripexplosive engine; and, generally stated, the."

invention consists of the novel devices and combinations of devices hereinafter described and defined in the claims.

In the accompanying drawings, which illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings, Figure 1 is a plan'view of the running-gear, frame and explosiveengine of an automobile to which 'the' invention is applied; Fig. 2 is a fragmentary vertical section taken on the line a as of Fig. 1, on an enlarged scale; Fig. 3 is a detail view in transverse section taken on the line m m of Fig. 2; Fig. 4 is a perspective view of the hot air discharge nozzle and a portion of the attached hot air conduit, some parts being broken away; Fig. 5 is a detail view, partly in side elevation and partly x in vertical section, taken on the irregular line m 01: of'Fig. 1, on an enlarged scale; Fig; Sis a view in transverse sectiontaken on the line w m of Fig. 1, on an enlarged scale; and Fig. 7 is a detail view, partly in side elevation and partly in section, taken on the line at m of Fig. 6.

Of the parts of the automobile illustrated for the purpose of showing the invention applied in working position; it is important to note the running-gear 1, frame 2, dashboard 3 and footboard 4 of the body, engine casing 5', exhaust manifold 6, exhaust pipe 7, muffler 8, radiator 9, fan 10, and hood 11.

Referring now-fi o the improved heater, the numeral 112 indicates a longitudinally extended casing open at its bottom, embracing the exhaust manifold 6 and extending thereabove. The longitudinal edges' of thecasing 12 are curved toward each other and closely engage the sides of the exhaust manifold 6, as. best shown in Fig. 3. The casing fipeciflcation of Letters Patent.

12 extends the full length of the exhaust manifold 6' and-its forward or receiving end is provided with a. flaring mouth 13, which opens rearward cache: radiator 9 and a sufficient distance therefrom to permit free operation of the fan 10. The rear end of the casing 12 is closed and is provided with an upwardly and rearwardly extended primary hot air discharge nipple 14 and a rearwardly and downwardly inclined secondarydho't air discharge nipple 15. f Y n A. flexible hot air conduit 16 is attached,

at one end, to the nipple 14, extends through an aperture in the dashboard 3 and has secured to its other orfree end a discharge nozzle 17. This nozzle 17 is adapted to loosely rest on the footboard 4 and, to prevent the same from rolling, is flattened in cross-section to substantially fan-shape, as

best shown in Fig. 4. To strengthen the nozzle 17 and prevent the same from crush ing in case the same is stepped upon, reinforcing bars 18 connect the upper and lower sides thereof. These reinforcing bars 18 give the open end o the nozzle 17 a cellular appearance. The casing 12 is rigidly secured to the engine casing 5 by nutequipped studs 19 on said. engine casing,

which project through depending slotted lugs 20 on the longitudinal edges of the casing 12.

Completely surrounding the exhaust pipe 7, just forward of the muffler 8, is a cylindrical secondary casing 21, having in its front end relatively large perforations, through which air is admitted to the casing.

A perforated damper 22 is mounted on the hub of the front end of the-casing 21 for oscillatory movements. This damper 22 may be oscillated to carry its perforations into registration with the perforationsinthe front end of the casing 21, or it may be oscillated into positions to partly or entirely close the front end of the casing 21.

A conduit comprising a flexible section 23 and a rigid section 24' connects the two casings 12 and 21. The flexible conduit section 23 is secured, atone end, to the nipple 15 of the casing 12, and the condui section 24 is rigidly secured, at one end, to t e front end of the casing 21 above the exhaust/pipe 7. The two conduit sections 23 and 24 are connected by a hand valve 25,'which may be turned to completely out off the passage'of hot air from the casing 12 into the casing 21. or it may be turned to govern the amount of through a flexible conduit 26 into the body of hot air passing through said conduit. As shown in Fig. 6, the damper 22 is notched to afford clearance for the conduit section 24 and permit a limited oscillatory movement of said valve. In actual usage of the heater, suitable operating rodsmay be at-- tached, one to the damper 22 and another to stem of the valve 25, for independently operating said damper and valve. These rods may be extended to points where they may be easily reached and operated by the driver.

Hot airfrom the casing 21 is delivered the automobile, preferably through the floor between the front and back seats. ceiving end of the conduit 26 is loosely telescoped onto'an upwardly projecting nipple 27, opening into'the rear end portion of the casing, and its upper endis loosely telescoped onto a flange nipple 28, The nipple 28 extends through the floor of the automobile and is secured in position by screws, not

through the radiator 9 will be forced by the fan 10 into the casing 12, through its flaring mouth 13, and into the conduits 16 and 23-24. Hot air passing through the conduit 16 will be widely distributed over the footboard 4 by the fan-like nozzle 17. The hot air passing through the conduit 2324 will be delivered into the casing 21 where it commi-ngles' with the hot air rising from the exhaust pipe 7. The hot air in the casing 21 is delivered through the conduit 26, under the action of the hot air. moving from the casing 12 into the casing 21, and the force of the air entering the open endof the casing 21, under the action of the traveling movement of the automobile. I

It is highly important to note that the exhaust manifold 6 inclines rearwardly and upwardly and that the top of the casing 12 extends substantially horizontal. By this arrangement, a large amount of the air, in entering the casing 12 passes over the exhaust manifold 6, but is gradually forced downward thereon. until it reaches the highest point of the exhaust manifold. As it is well known, the highest point of the exhaust manifold is the hottest and often becomes red hot. The air in passing through the radiator 9 is slightly warm and. in passing through the casing 12. is gradually heated, until it reaches the highest point of the ex- The reinto the automobile body haust manifold 6. Here, the volume of heated air is reduced and made very hot before entering the delivery conduits 16 and 23 24. By closing the valve 25, the casings 12 and 21 may be independently operated.

'That is, all ofthe heat from the exhaust manifold -6 may be delivered into the conduit 16 andall of the heat of the exhaust pipe 7 within'the casing. 21, may be delivered into the conduit 26. Or the valve 25 may be partly closed to limit the amount of hot air passing from the casing 12 into the casing 21. By flexibly connecting the nozzle 17 tc the casing 12, said nozzle may be set in different positions on the footboard 4, or it may be lifted up, as indicated by dotted lines in Fig. 2, so as to be out of the way, when it is necessary to remove the footboard 4. Footboards of automobiles are made removable to afford access to the engine. It is, of course,

understood that the flange nipple 28 may be located at any desired point in the automobile. It is, also, evident that the improved heater may be applied to an auto-, mobile, as shown in the drawings, or it may be applied in separate units, the one including the casing 12 and the other the secondary casing 21. The flexible hot air delivery conduits 16, 23 and 26 take up all vibrations and permit independent movements of the various parts of the improved heater, which they connect. They also, make it an extremely simple matter to apply the improved heater tothe automobile and to adjust the various parts thereof. The secondary casing 21 is slidably mounted on the exhaust pipe 7 and is held in different adjustments thereon by a set screw 30. carried by the hub at the rear I end of said casing.

As shown in Fig. 7 the secondary casing 21 is covered with an insulating material 31 held in position by bands 32. When the automobile is standing still the damper 22 may be closed to prevent the intake of-air, Which would cool the air within the casing '21, to conserve the heat arising from the exhaust pipe 7.
